Event Format

The Forestry CDE shall consist of the following six (6) components:

A. General Knowledge - 30 minutes

1. This phase of the contest will test the contestant's knowledge and understanding of basic

forestry and agroforestry principles.

2. Contestants will see fifty (50) objective type, multiple choice or true/false questions

reflecting the contest objectives and coming from the reference list.

B. Tree Identification - 30 minutes

1. Twenty (20) unduplicated specimens from the list on Form 40 will be displayed for

contestants to identify by common names. Duplicate samples may not be used in any

identification portion of the event. 2. Each specimen will be designated by a number

3. Contestants will have approximately one and one-half minutes for each specimen station.

4. Specimens may be actual specimens or mounted specimens.

C. Equipment Identification - 10 minutes

1. Twenty (20) pieces of equipment from the list on Form 41 will be displayed for

contestants to identify by proper technical name. Duplicate samples may not be used in

any identification portion of the event. 2. Each piece of equipment will be designated by a number.

D. Timber Cruising (measuring standing timber on a 1/10 acre plot) - 60 minutes

1. Using a Biltmore tree scale stick, in the correct manner, each contestant will measure pre-

numbered trees on a 1/10 acre plot for DBH, 4.5 ft. from the high side of the tree, tree

height to the nearest 1/2 log (8') and board foot volume.

2. All marked trees on the plot must be measured in order to make the desirable cruise

computations, but only the first five trees (saw timber) will be scored for each individual

measurement.

3. WHILE TREE FORM AND MINIMUM MERCHANTABLE TREE DIAMETERS

VARY ACROSS THE STATE, TO LEVEL THE PLAYING FIELD FOR THIS PART OF

THE CONTEST, TREE VOLUMES SHOULD BE DETERMINED USING THE

FOLLOWING GUIDELINES:

a. Given a general Form Class of 75, one can expect to lose one inch diameter (outside bark)

for every eight-foot log.

b. Minimum merchantable tree diameter will be ten inches (outside bark).

c. Merchantable volume will stop at the first major fork or obvious defect in the trunk.

d. No volume is to be determined for logs above the fork (or defect) as well as any side limbs.

e. After measuring all trees, the contestant will find total volume per acre, total value per acre,

the average DBH per acre, the total number of trees per acre, and the desired minimum

number of trees per acre. The student will then decide if the stand was understocked,

adequately stocked, or overstocked. The student will then recommend that the stand be

thinned, harvested, or left to grow.

1. Harvest: The removal of all or portions of the trees on an area. If the average

diameter on the 1/10 acre plot is 12 inches or greater and is definitely overstocked, a

harvest cut is possible.

2. Thinning: A cut in an immature forest stand to reduce the tree density and to

concentrate productivity on fewer, higher quality trees. Usually the average diameter

is less than 12 inches and the stand is overstocked.


3. Left to grow: The stand is not overstocked and the trees can be left to grow to

maturity, a larger average diameter, or until further management is necessary.

f. A chart showing the desirable stocking level will be provided and a chart with the

International 1/4" Tree Scale will also be provided.

E. Timber Stand Improvement (TSI) - 30 Minutes

1. The site will be a fixed area, normally 1/10 acre or (merely designated).

2. All trees will be identified by number.

3. On the scorecard, the student will be given the following information:

a. existing number of trees per acre

b. number of trees to thin (or leave) per plot

c. objective or management plan for the stand

4. Using the information furnished on the scorecard, the student will determine whether

each tree will be:

a. left for growing stock or

b. deadened/remove for a cull or undesirable species/harvest

5. The management plan will be explicit in scope giving all information needed by the

student to decide whether to cut, leave, or deaden.

a. If the plan is for timber production, it will state the species which are desirable

and those that are undesirable and size and quality limits of merchantable trees.

b. If the plan is for wildlife habitat management, the plan is to include the species

desirable and undesirable, number of den trees needed per acre, and the number of

foresting trees to be left per acre.

6. Additional information, as appropriate, may be included.

7. NOTE: Cutting of firewood is not to be considered a harvest operation.

8. Only those trees 4" DBH and larger will be tagged or numbered.

F. Map Reading - Legal Descriptions - 20 minutes

a. Contestants will be furnished a U.S. geological survey map with specific points marked

for the student to identify.

b. The student will need to know legal descriptions, size or location of no less than one 10

acre land parcel.

c. When the student is asked to identify points on a geological survey map, the points will

be clearly marked with a letter and an arrow pointing to the section or symbol or area on

the map to be identified or sized.

Examples are:

(1) Find Letter A--What is the legal description of the area boxed in? southwest one quarter

of the northwest one quarter of the northwest one quarter of section

(2) Find Letter B--What is the item located at this point? Church

(3) Find Letter C--What is the acreage of this point boxed in? 10 acres

(4) Find Letter D--What is the line shown here called? contour line

1. Scoring Timber Crusing

a. There are a total of 100 points possible in this section.

b. Fifty (50) points will come from proper measurement of the first five saw timber trees.

This would be ten points for each tree:

•Two points for correctly identifying the tree species

•Four points for correctly measuring DBH

•Four points for correctly measuring proper tree height to the nearest 1/2 log.

c. The remaining 50 points will come from answering questions about measurements:

•10 points for total volume per acre (allowing for a variance of plus or minus 10 percent)

•10 points for value per acre (allowing for a variance of plus or minus 10 percent)

•10 points for minimum number of trees per acre

•10 points for assessing stand (understocked, adequately stocked, or overstocked)

•10 points for determining if the stand should be thinned, harvested, or left to grow

2. Tie scores among teams in all events should be broken using the high individual team

member's score. In case the scores are tied, the scores of the second high individual on each

team should be used.

Event Rules and Regulations

1. Under no circumstances will any contestant be allowed to touch or handle plant material

during the contest, with the exception of the tree measuring activity. Any infraction of

this will be sufficient cause to eliminate the team from the contest.

2. Observers will not be permitted in the contest area while the contest is in progress.

3. No contest team, team member, or team coach shall visit the contest facilities to observe

plant materials and facilities prior to the contest.

4. Any contestant caught cheating during the contest will, along with his/her team members,

be expelled from the contest.

5. All contestants are expected to be prompt at their stations throughout the contest. No

provisions will be made for tardiness and will most certainly cause late contestants to lose

contest points.

6. Contestants will be assigned to group leaders who will escort them to various contest

staging lines. Each contestant is to stay with his or her group leader throughout the

contest or until told to change leaders by the contest superintendent.

7. All contestants will be given a contestant number by which they will be designated
